摘要：
A conduit for conducting ions from a high pressure ion source to a mass analyzer in mass spectrometry apparatus includes a capillary tube in which the lumenal surface of the bore near at least one end is a surface of an electrically conductive material. In one embodiment the conduit is constructed of a dielectric material and has an electrically conductive coating on an end portion of the lumenal surface.
